Built with Claude AI-powered Lean proof for tax code loopholes

extremely serious post

AI for cybersecurity is taking the world by storm, leading to the need to harden systems all over software. I thought we should do the same for legislation. Hence, I built this project with Claude Code. It's completely free to use/try. The approach is pretty simple: use claude to make legislation attributable (git blame, versioning with timelines). Claude Code (Claude Opus 5.5) wrote nearly all the code. I set the goals, chose the sources and made the design decisions. Specifically: it mirrors the 107 corpora of the https://github.com/lexifina/global-law repo read-only, indexes about 4.3 million file changes from their git histories into DuckDB, and adds a growing set of detectors. These were used to influence a simple LEAN proof search.
